问题 I am compiling on a 64 bit architecture with the intel C compiler. The same code built fine on a different 64 bit intel architecture. Now when I try to build the binaries, I get a message "Skipping incompatible ../../libtime.a" or some such thing, that is indicating the libtime.a that I archived (from some object files I compiled) is not compatible. I googled and it seemed like this was usually the result of a 32->64 bit changeover or something like that, but the intel C compiler doesnt seem

问题 I'm looking for a solution to send a Push Message from PHP in Intels App-Framework, but I can't find any good solution. I have found this: https://gist.github.com/prime31/5675017 But how can I get the DEVICE_REGISTRATION_ID? It's very difficult to find some code or solution. 回答1: Ive found the Solution. I have forgott to type the IP 0.0.0.0/0 into the Google API Console. And i added the Google API Key and Projectnumber by the Push Category on Build Window. Then i copy paste the code from http

问题 I'm compiling data to compare CPU and GPU GFLOP performance, and I'm looking currently at dual socket CPUs (E5-26xx family), however after Broadwell comes Skylake architecture which has Bronze and Silver dual processor families, but they have half the cores and performance than the Broadwell ones. Am I missing something? 回答1: Interesting, it seems you're right that the only high-core-count Skylake-server chips are also capable of being used in 4-socket systems. (https://en.wikichip.org/wiki

问题 how can i build my application that work on devices with Intel CPU ? my application work on devices with arm technology but when i try to install my app on device with Intel CPU it`s show this message : Devicenot compatible and this message on log : Failure [INSTALL_FAILED_CPU_ABI_INCOMPATIBLE] this is my project build.gradle file : apply plugin: 'com.android.application' android { compileSdkVersion 19 buildToolsVersion "19.1.0" defaultConfig { applicationId "com.test.test" minSdkVersion 16

问题 There is a bug in intel compiler on user-defined reduction in OpenMP which was discussed here (including the wrokaround). Now I want to pass the vector to a function and do the same thing but I get this error: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted This is the example: #include <iostream> #include <vector> #include <algorithm> #include "omp.h" #pragma omp declare reduction(vec_double_plus : std::vector<double> : \ std::transform(omp_out

问题 Is there a way to determine, for some progamatically defined interval, if a SMM entry has occurred on the current core? 回答1: Starting with Nehalem, the MSR register 0x34 (called MSR_SMI_COUNT ) counts the number of SMIs that occurred since the system was booted. It's read-only and Intel-specific. You can programmability read from this register (or any other MSR register) from user mode using the /dev/cpu/CPUNUM/msr interface. There are several tools that use the interface to show the SMI

问题 I'm using Intel Advisor to analyze my parallel application. I have this code, which is the main loop of my program and where is spent most of the time: for(size_t i=0; i<wrapperIndexes.size(); i++){ const int r = wrapperIndexes[i].r; const int c = wrapperIndexes[i].c; const float val = localWrappers[wrapperIndexes[i].i].cur.at<float>(wrapperIndexes[i].r,wrapperIndexes[i].c); if ( (val > positiveThreshold && (isMax(val, localWrappers[wrapperIndexes[i].i].cur, r, c) && isMax(val, localWrappers

问题 Why did Meltdown and Spectre bugs go undiscovered for so long? Nearly 20 years these bugs have been present in the CPU's why wasn't this discovered sooner given the serious implications for all computers using these processors? 回答1: The answer is quite simple: modern CPUs have few billions transistors. For example, the latest Intel Skylake architecture has ~2 billion. Each transistor might have a state which influence the state of other transistors (i.e. those transistors are connected

问题 I am trying to install HAXM for my Android studio, after I downloaded the installer from the official site and tried to run it, a extracting dialog flashed up and disappeared immdiately. Then I can see the installer in my task manager, but nothing pops up, not even the setup screen that's supposed to show up. This is what's supposed to show up: After a while, the installer entry in my task manager just disappear by itself. I tried to run it on my friend's laptop and it worked properly. I

问题 What does the below comment mean in Intel Processor data sheet? How can I check that in my driver's code in Linux? If CPUID.06H:EAX.[7] = 1 I come across this type of statements in the SW developer's manual for Intel Processors in the comments column in register description table.. Ref: https://software.intel.com/sites/default/files/managed/22/0d/335592-sdm-vol-4.pdf Please help me to understand the processor descriptions. Thanks. 回答1: CPUID.06H:EAX.[7] enables the discovery of the HWP
